Surgical aneurysmectomy restores normal cardiac size in an infant with a giant LAA aneurysm.
Case Report (n=1)
Surgical aneurysmectomy successfully restored normal cardiac size in an infant with a rare congenital giant left atrial appendage aneurysm.
Supports surgical consideration in rare congenital giant LAA aneurysm; hypothesis-generating and requires prospective validation before practice change.
Left atrial appendage aneurysm (LAAA) is an extremely rare congenital heart abnormality, with varying degrees of symptoms, ranging from asymptomatic to arrhythmia, thromboembolic event or airway obstruction. Most infantile cases were incidentally found by echocardiography. Contrast-enhanced chest tomography can confirm the diagnosis and inform surgical plan. We describe an asymptomatic young female infant who had a unique extreme cardiomegaly on a chest x-ray and received surgical aneurysmectomy. Her heart was restored to a normal cardiac size after the heart surgery.
